This was possible since for all analyses, the gonads of each larva were placed on the same microscope slide as the polytene chromosomes. Genomics 18 : —, [ PubMed ] [ Google Scholar ]. Sign In.

Antigens of human pancreatic adenocarcinoma cells defined by murine monoclonal antibodies.
In contrast to males where genes from only one X chromosome are present, the occurrence of two X chromosomes in females gives rise to the potential expression of twice the amount of X chromosome DNA in females compared with males. Table 1 Taxa of the Simulium arcticum complex.
The 46 break points in common among taxa may be an overestimate because do all organisms contain sex chromosomes for male and female sign in North Bay is difficult to determine specifically the exact breakpoint in regions between obvious chromosome bands.
In recent years, DNA sequences on the Y chromosome linked with the sex-determining gene have been discovered in most species of genus Oncorhynchus.
For example, male embryos created through in vitro fertilization grow faster prior to implantation than female embryos 6 , , These differences between sockeye salmon and other salmonids have made it difficult to detect the location of the sex-determining gene and identify sex-associated loci in this species.
A role for cell sex in stem cell-mediated skeletal muscle regeneration: female cells have higher muscle regeneration efficiency. Geographical versus ecological isolation of closely related black flies Diptera: Simuliidae inferred from phylogeny, geography, and ecology: Implications for speciation in black flies Diptera: Simuliidae.
BMP4-expressing muscle-derived stem cells differentiate into osteogenic lineage and improve bone healing in immunocompetent mice.
